PURPOSE: To aim at compactness by disposing a pair of gears of the odd number of speed change stages on a side of one counter shaft and a pair of gears of the even number of speed change stages on a side of the other counter shaft between the right and left counter shafts and an output shaft arranged parallel to the counter shafts, respectively.
CONSTITUTION: Transmitters such as sears GA, GB are interposed between the central portion of a crankshaft A of an engine and an input shaft 1 of a change gear. Hollow counter shafts 3A, 3B are coaxially disposed on both sides of the input shaft 1. Clutches C1, C2 are arranged in such a manner as to connect and disconnect the input shaft to and from the right and left counter shafts. A pair of gears having the odd number of speed change stages and a pair of gears having the even number of speed change stages are provided on the counter shaft side between the counter shafts and an output shaft 2 and on the output shaft side therebetween, respectively. One gear of each pair is fixed to the counter shaft while the other gear thereof is detachably disposed in the counter shaft via fixing means (synchronizer mechanisms) SR4, S2, S13, S5. Therefore, any interruption of a drive force can be prevented in the speed change without enlarging an engine room even in an FF or RR system.
